Presently, about 65% of Africa's population is constituted by the "youths". The United Nations defines youth as persons between the ages of 15 and 24 years. According to the United Nations, Africa has the youngest population in the world, with an estimated 226 million youth aged between 15 and 24 years in 2020. This accounts for about 19% of the global youth population. Furthermore, the African continent has a rapidly growing population, with projections indicating that the population could double by 2050.
